MSTN LCD DRIVER IC UC1603i

Single-Chip, Ultra-Low Power
68COM x 98SEG Matrix
Passive LCD Controller-Driver
INTRODUCTION
UC1603i is an advanced high-voltage mixedsignal
CMOS IC, especially designed for the
display needs of ultra-low power hand-held
devices.
This chip employs UltraChips unique DCC
(Direct Capacitor Coupling) driver architecture to
achieve near crosstalk free images.
In addition to low power COM and SEG drivers,
UC1603i contains all necessary circuits for
high-V LCD power supply, bias voltage
generation, temperature compensation, timing
generation, and graphics data memory.
Advanced circuit design techniques are
employed to minimize external component counts
and reduce connector size while achieving
extremely low power consumption.
MAIN APPLICATIONS
Cellular Phones, and other battery operated
palm top devices or portable Instruments
FEATURE HIGHLIGHTS
Single chip controller-driver for 68x98
graphics STN LCD panels.
